y Yosfr," a citizen oi, the `United States, and a'. resident of York,county of York, State oi Pennsylvania', have `.invented certain new andusetul linprovernents in laper-Registering Devices, of whichtheiollowingI is a specifica This invention relates to a paper registering`device v.for properly positioning sheets The object of this inventionis to provide a paper registrating device ci a character which can beattached at any location to the :tace ofa `printing` press platen andthereby "rendering thesarne adaptable for useV on Verysrnall as wellasflargesheets olf` paper;

A `further object is to construct a `device ot this kindofthe smallestpossible size; this a very important feature for the reason that thereis` seldom if `ever inuch Space available at the point where it isnecessary forthisdevice to be placed for performing its functions.` Theprinting` press constructions `of the present day` does not afford `muchroorn for a device oit `this kind. y `Another object of this inventionis to construct `a practical operative device, of the character hereinshown and described, which has practically all its working partsenclosed in substantially a dust proof casing, so that thesanie isdurable and otherwise `iool` proof. y

@ther objects will be apparent, andthe nature and scopeof this inventionwill be `more fully understood, from the following` description, takenin connection with the accompanying drawings, 'forming `a part hereofand, in which similar numerals refer to similar parts throughout theseveral views.

Fig.`1,`is anenlarged view of a paper registering'device attached to theplatenot a printing press, and is shown in operating condition."

` on line 2-2.`

fFig. 2, is a sectional view 01""Fig. 1, taken `Fig. 3, is a` view oitthe paper registering device with the topplate rernoved, showing theinternal mechanism.`

Fig. 4, represents certain essentialparts of" a printing, press `withwhich this paper registering device co-"operates,

Referring to the drawings., l is a base section `of the paperregistering device and carriesaboss 3 upon Lwhich is journaled thedislrt; rllhe top plate 5 is: provided with a disk Ll on the besscounter bore 6 which lits neatly on the boss 3 and held firmly theretoby the screw 7.

ln addition to being-g bored to tit the boss 3, the dist: l is providedwith an opening 8 60 to provide space tor the spring 9 and the stop-pinl0. Foruling` part of the base section l is a projectionor pin il,around which is woundthe spring 9 as shown. rlhe spring` 9 normallyturns the dish Ll in the di- 65 rection indicated by the arrow l2,relative to the base section, until it is prevented troni turning bycoming7 in contact with the pin l() at thepoint i3.

, Forming,I part of the disk l is a lug la, 70

cord l5 being attached to the saine through the linlrl which lits intothe hole 17 as shawn. "W hen tension is applied to thecord i5, the dislr4 turns on the bess 8 against t the action oit the spring,` 9, andcarrieswith it the paper gripl ing clips 3 8 and 19, the same being`lirnily iixed thereto by solder or other means. N

The printi 1,- press platen 2O is covered with padding- .Z1 in the usualinanner. Sol- 80 dered to the rear side elf the base section l areneedles which are inserted `into the padding; 2l 'to hold the paperregistering device to the irintinp pre-ss platen.

The operation of this device is as follows:

The paper registering device is fixed to the printing,l press platen atthe location indicated at it., Fig. fr. rlhe cord 'i5 is led downwardand '(irnily tied to the eye pin 23. lt is very apparent to thoseskilled in the art, hcw tension will be applied to the cord l5 duringthe operation oli the printing press when connected as above described;in that,

20 the paper holder 3l. nieves in the direction 95 indicated by thearrow relative to the platen, 'the saine tiuning; on the pivot 25.

As this occurs the end oi: the eye pin 23 moves in thedirectionindicated by the arrow relative to' the platen, thereby `ap-100 plying` tension to the cord l5 and turns the The paper grippingclips 18 and 'i9 are thereby moved in the direction indicated the arrow27, Fig. l. rllhe length olf the eye pin 23 and the cord l5 105 niust besuch i. thy the paper gripping clips will be carriedironi the positionshown in liull lines in Fig, l, to the position shown does not interfererally lind its way between the paper gripping clips i8 and 19; thetension of these paper gripping clips being just su'licient to giveenough gripping action on the paper so that during the movement of thepaper gripping clips from Athe position shown in full lines l, totheposition shown in light broken lines, theyr will carry the paper insubstantially the direction indire-ted b v the arrow 30, until the edgeof the paper comes in'contact with the stops 28 at which time the paperis in perfect registration;

`vthe paper gripping clips continue to move forward, sliding on thepaper, and hnally release their gripping action upon the same entirely;this must occur before the platen presses the paper against the type sothat it with printing en the en tire surface of the paper.

It is obvious that all the adjustments must be such .whereby the paper29 is perfectly registered by this device before the paper holder 3larrives at the position indicated by 3l', for the paper holder is thenholding the paper firmly against the platen to prevent the same fromshifting, and under this condition the registering device cannot movethe paper to bring it to perfect registration.

In constructing a device of this character I `prefer to have the papergripping clips inclined slightly from vertical position in the directiontoward its forward movement as shown in Figs. l and 3; because I have.found that if they are vertical, there is too much elfort applied tomove the paper against the side paper stops, relative to that appliedfor pulling` it down against the lower stop.

Having thus described my invention what I claim and desire to secure byUnited States Letters Patent is as follows:

l. In combination with a printing press having` a platen and a movingcrank element, of a base element, means for attaching said base elementat any point on the face of the platen, a lever pivoted to said baseelement, paper gripping means carried by Vsaid lever, a flexible cordconnecting said lever with said crank element and adapted to move saidlever through the action of said moving crank element, and means forreturning said lever to normal position.

2. A; paper registering device comprising a base element, needles fixedto a said base element, a lever pivoted to said base element, a flexiblecord attached to said lever, a stop for limiting the movement of saidlever, a spring for normally holding said lever against said stop, andpaper gripping means carried by said lever.

3. A paper registering device com rising a circular base element, acircular disli journalcd thereon, a stop for limiting the movement ofsaid circular disk, a spring for normally holding said disk against saidstop, a lug carried by said circular disk and pro jecting beyond saidcircular base element, paper gripping means carried by said circulardisk, and a plate fixed to said circular base element and substantiallyenclosing said circular disk, said spring and said stop in a dust proofcase.

4T. A paper registering device comprising base element, means forattaching said buse element to a printing press platen, a level' pivotedon said base element, a stop for limiting the movement of said lever, aspring for normally holding said lever against said stop, paper grippingmeans carried by said lever, and means for moving said lever against theaction of said spring in unison with the movement of the said printingpress platen.

5. A paper registering device comprising a circular base element, acircular disk journaled thereon, means for attaching said base elementto a printing press platen, a stop for limiting the movement of saidcircular disk, a spring` for normally holding said circular disk againstsaid stop, a lug carried by said circular disk and projecting beyondsaid circular base element, paper gripping means carried by saidcircular disk, a plate iixed to said circular base element andsubstantially closing said circular' disk, said signing and said stop ina dust proof case, and means for moving said disk through said lugagainst the action of said spring iu unison with the movement of thesaid printing press platen.

G. A paper registering device comprising a base element, needles forattaching said base element to any point on the face of a printing pressplaten, a lever pivotcd to said base element, a stop for limiting themoif'ement of said lever, a spring for nor mally holding said leveragainst slid stop, paper gripping means carried by said lever, and meansadapted to move said lever against the action of said spring in unisonwith the movement of the said printing press platen.

7. A paper registering device comprising a base element, a lever pivotedthereto, :l stop for limiting the rearward movement of said lever, aspring for normally holding said lever against said stop, and papergripping means liXed to the hub of said lever, the same beingslightlyinclined from vertical position in the direc-tion toward its forwardmovement when said lever is against said stop.

In testimony whereof I allix my signature.
